staticwater Posted April 30, 2014 Author Report Posted April 30, 2014 Idea a fost urmatoarea: @sulea you never stop amazing me! Ai VIP de la mine Ce metode ai folosit? Function hook, memory dumpers? Quote
sulea Posted April 30, 2014 Report Posted April 30, 2014 ma sfatuiam aseara cu user6 despre cum sa abordam crackmeul, i-am spus ca este vorba de un exe intr-un alt exe, un fel de wrapping. i l-am recomandat pt ca se ocupa de malware si crackmeul are potential de malware(manipuleaza exeul cel mic, PE header, sectiuni etc). ma gandeam la un moment dat sa fac dump, dar lui ida ii trebuie script pt asta, asa ca am renuntat.si din vorba in vorba.. daca vrei neaparat iti voi spune metoda folosita, insa prefer sa zic doar ca m-am folosit de o slabiciune de-a ta iar ca tool s-a folosit exclusiv ida Quote
